Modify “new user” email

I’d like to modify the email that new users receive after they register. Specifically, I’d like to add some textual instructions on how to change their password. Is there a plugin that allows me to do this?

There is no plugin that I know of. I wanted to do the same thing, so I just modified the core file ./bb-includes/registration-functions.php around line 101. One of these days I will figure out how to write a plugin…

I wouldn’t recommend changing core files on a regular basis. I do it because I don’t know how to create a plugin (yet.) I also keep a list of modifications to the core files. That way, when another version comes out, I can apply my changes to the new core files. Hopefully, in the future, I won’t need to do it like that, but for now, it’s all I can do.
